TOILET BOWL FLUSH TANK DISINFECTANT CONTAINER Filed Aug. 29, 1950 myaw m ATTEI RN EYS Patented Dec. 9, 1952 PATENT; OFFICE TOILET BOWLFIUSH TANK DISINFECTANT Antone Nunes Vierra, Honolulu, v a Territory of Hawaii 7 V V d putation August 29, 1950 Serial No. 1s 2-',07o f i 2 "chime; (01. 4-227) This invention relates containers "for.

infeetants particularly of'the' type used in. flush tanks of toilet bowls, and in particular a tank having an outlet nipple in the lower end with threaded nipple on the upper end aligned with the outlet nipple and having a cap with a valve.

suspended by a valve stem from the cap and positioned to coact with the outlet nipple, a threaded filling nipple having a cap thereon positioned. in the upper end of the tank, and a vent tube extended from the outlet nipple below the lower end of the tank to a point corresponding with the upper end'of the tank.

'I'he purpose ofthis invention is to provide animproved vent for a disinfecting container for flush tanks of toilet bowls wherein a small charge of disinfeetant is dispensed with the flushing of the bowl.

Various types of devices have been provided for supplying disinfectant to flush tanks of toilet bowls and to the bowls direct and someof these are actuated by the rise and fall of water in the tank but it has been found difficult to provide a vent that permits a small quantity of air to replace disinfectant in the container that operates with each flushing of the tank. With this thought in mind'this invention contemplates a disinfectant containing tank having a small tube providing a vent extended from a point just below the valve seat in an outlet nipple of the tank to a point adjacent the upper end of the tank above the high water level of the flush tank.

I tube secured to the wall at spaced points and a disinfectant container for flush tanks of toilet I- bowls that may be installed in tanks now in use without changing the design or construction thereof.

A further object of the invention is to provide an improved vent tube or disinfectant container for flush tanks of toilet bowls which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a disinfectant container having a depending outlet nipple or spout with a valve in the upper end of the spout and with a small vent tube connected to the nipple and spaced from and extended "upwardly on the outer surface of the wall thereof with the with the upper-end ofthe tube extended to a 01111: corresponding with theupper end of the an i Other features and advantagesof the invention will appear from the following description taken in connection with the'drawings wherein: v

Figure l is a cross section through the flush tank of a toilet bowlshowing the position of the disinfectant container therein.

Figure 2 is a vertical section through the disinfectant container or tank. showing the vent tube on one side thereof and with the tube shown in elevation.

Figure 3 is a detail on an enlarged scale illustrating the connection of the lower end of the vent tube with the outlet nipple or spout of the tank. Y

Referring now to the drawings wherein like reference characters denote corresponding parts the improved disinfectant tank of this invention includes a tank In having an outlet spout H at the lower end, a threaded nipple I! on the upper end and aligned with the outlet spout, a filling nipple I3, a valve 14, and a vent tube [5.

In the design shown, the valve seat It is provided around the upper end of the spout I I and the lower conical shaped surface I! of the valve [4 coacts with the seat I6 to close the lower end of the tank when the device is in an inoreprative position. When the device is set for use the valve I4 is actuated by a head [8 on the valve stem 19 which is threaded through a lug 20 on the inner surface of a cap 2| whereby the surface I! is positioned slightly above the seat It so that a small opening is provided around the upper end of the spout in the lower end of the tank.

The stem 19 is provided with a lock nut 22 whereby with the parts adjusted to provide a desired opening in the valve elements the nut 22 is turned against the lower end of the lug 2|] to retain the parts in position.

The filling nipple I3 is provided with a closure cap 23 and the container may be provided with a hook 24 by which it may be suspended from a wall 25 of a flush tank as indicated by the numeral 26. The tank or container In is held by bands 21 and 28 on the hook 24 and it will be understood that the tank or container may be suspended in the flush tank by any means or in any suitable manner.

The vent tube l5 opens into the spout ll through an orifice 29, as shown in Figure 3 and the tube may be attached to the outside of the wall of the tank by lugs 30, 3| and 32 as shown in Figure 2 or may be incorporated therein as may be desired.

With the parts arranged in this manner the tank or container in is positioned in a flush tank of a toilet bowl or the like and with the valve [4 adjusted from the upper end of the stem IS, a comparatively small opening is provided in the lower end of the tank. With water in the tank extended upwardly above the lower part of the tank or container l0, disinfectant is sealed in the tank and as the water level drops below the lower end of the opening 29 of the vent [5, air is admitted to the container I whereby a small amount of disinfectant is per mitted to drop downwardly through the spout or nipple l l and into water in the tank.

The container may be refilled without disturbing the valve [4, through the nipple [3 with the cap 23 removed.

It will be understood'that modifications may be made inthe design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is: 1. In a flush tank disinfectant container, the combination which comprises a tank having a depending outlet nipple on the lower end with a valve seat in the upper end of the nipple, 'a valve positioned-to coact with the valve'seat, a threaded nipple on the upper end of the tank aligned with the outlet nipple, a valve stem on the lower end of which the valve is carried extended through the threaded nipple on the upper end of the tank, a cap threaded on-the said threaded nipple on the upper end of the tank through'which the valve stem extends, and means adjusting the position of the valve stem in said cap, and a vent tube arranged exteriorly of said tank and having its lower end communi- 4 eating with the upper portion of said spout be- 4 low the valve seat and having its upper end terminating above the top of said tank.

2. In a flush tank disinfectant container, the combination which comprises a tank having a plurality of threaded nipples positioned on the upper end and having an outlet spout extended downwardly from the lower end and aligned with one of the said threaded nipples on the upper end, a vent tube extended from'the upper end of the outlet nipple to a point above and exteriorly of the upper end of the tank and com municating with the upper end of the said outlet nipple, caps threaded on the threaded nipples on the upper end of the tank, a valve stem threaded in the cap of the nipple aligned with the outlet spout and having a valve member on the lower end positioned to coact with the upper end of the outlet spout, and means locking the valve stem in adjusted positions, said vent tube being arranged exteriorly of said tank and having its lower end communicating with the upper portion of said spout and having itsupperend;

terminating above the top of said tank.
